Question

(x−30)(x−8)(x+2,2)=0 ​

Answer 1

Ответ:

Пошаговое объяснение:

Первый корень уравнения:

х-30 = 0

х1 = 30

Второй корень уравнения:

х-8 = 0

х2 = 8

Третий корень уравнения:

х + 2,2 = 0

х3 = - 2,2

Answer 2

To solve the equation $(x - 30)(x - 8)(x + 2.2) = 0$, you can use the zero-product property, which states that if the product of two or more factors is equal to zero, then at least one of the factors must be equal to zero. In this case, you have three factors:

1. $x - 30$
2. $x - 8$
3. $x + 2.2$

Set each factor equal to zero and solve for $x$:

1. $x - 30 = 0$ Add 30 to both sides: $x = 30$

2. $x - 8 = 0$ Add 8 to both sides: $x = 8$

3. $x + 2.2 = 0$ Subtract 2.2 from both sides: $x = -2.2$

So, the solutions to the equation are $x = 30$, $x = 8$, and $x = -2.2$.
